Hello community,
im struggling now for a while with Wireguard and IPv6. My ISP is providing me an ipv6-pd/56 address.
Here you can have a look:
So i have a peer now which is configured as followed:
client PJ
config wireguard_WG0
option description 'PJ'
option public_key 'PUBLIC KEY CLIENT PJ'
option route_allowed_ips '1'
list allowed_ips '192.168.20.8/32'
list allowed_ips 'fd42:42:42::2/128'
and here is the OpenWRT router
config interface 'WG0'
option proto 'wireguard'
option private_key 'PRIVATE KEY ROUTER'
option ip6assign '64'
list addresses '192.168.20.1/24'
list addresses 'fd42:42:42::1/64'
option listen_port '51902'
option mtu '1280'
list ip6class 'wan6'
and here is the Wireguard config on the client side
PJ CLIENT
[Interface]
PrivateKey = PRIVATE KEY
Address = 192.168.20.8/24, fd42:42:42::2/64, fd3b:ec65:a318::2/64, 2003:c7:4f48:4300::2/64
MTU = 1420
[Peer]
PublicKey = PUBLIC KEY ROUTER
Endpoint = mydomain.net:51902
AllowedIPs = 0.0.0.0/0, ::/0
When i try to bring this up i get something like this
interface: wg0
public key: PUBLIC KEY CLIENT
private key: (hidden)
listening port: 56077
fwmark: 0xca6c
peer: PUBBLIC KEY ROUTER
endpoint: [2003:c7:4fff:4988:a80a:61af:c5c6:95db]:51902
allowed ips: 0.0.0.0/0, ::/0
transfer: 0 B received, 888 B sent
